Guys need help , A little confuse here,is it the lower balljoint that will need replace after 90k miles or the upper balljoint. Which one is more important to replace first. I don't want my wheels to fall off. lol Its hte lower one that we been talking about right.

 

Lower...but if you doing that...u might as well do the upper at the same time.

 

its the lower .. upper is part of the a arm which is very expensive but should not need replacing unless boot is torn

 

thanks guys
